摘要:
A catalyst composition useful for producing olefins and aromatic compounds from a feedstock is formed from a fluidized catalytic cracking (FCC) catalyst and a ZSM-5 zeolite catalyst, wherein the amount of ZSM-5 zeolite catalyst makes up from 10 wt.% or more by total weight of the FCC catalyst and the ZSM-5 zeolite catalyst. The catalyst composition may be used in a method of producing olefins and aromatic compounds from a feedstock by introducing a hydrocarbon feedstock and the catalyst composition within a reactor, at least a portion of the reactor being at a reactor temperature of 550°C or higher. The feedstock and catalyst composition are introduced into the reactor at a catalyst-to-feed (C/F) ratio of from 6 or greater.
摘要:
A method of producing olefins and aromatic compounds from a feedstock includes introducing a hydrocarbon feedstock and a catalyst composition that is suitable for converting the feedstock to at least one of olefins and aromatic compounds within a reactor. The reactor has a reactor flow path having a length L between the inlet and outlet. The temperature in the reactor is monitored in at least one location that is at or adjacent to the inlet at a temperature-monitoring distance that is from 0.3 L or less from the inlet. In response to the monitored temperatures one or more parameters are modified. At least a portion of the feedstock is allowed to be converted to at least one of olefins and aromatic compounds within the reactor, which are removed as a product stream.
摘要:
A method of producing olefins and aromatic compounds from a feedstock is accomplished by introducing a hydrocarbon feedstock and a catalyst composition within a reactor. At least a portion of the reactor is at a reactor temperature of from 470° C. to 730° C. The catalyst composition is comprised of a fluidized catalytic cracking (FCC) catalyst and a ZSM-5 zeolite catalyst, wherein the amount of ZSM-5 zeolite catalyst makes up from greater than 0 wt. % of the total weight of the FCC catalyst and the ZSM-5 zeolite catalyst. At least a portion of the feedstock is converted to products of at least one of olefins and aromatic compounds within the reactor, with at least some of the products being contained in a liquid product stream. At least a portion of the liquid product stream is directed to different downstream processes to increase production of at least one of olefins and aromatic compounds.
